Product Details
This sea water pump mechanical shaft seal is a replacement seal for compatible Jabsco raw-water pump applications. It is intended to restore the pump shaft sealing function and help prevent water from reaching the pump bearing area. The product is supplied as a single mechanical shaft seal, not as a complete water pump or a multi-piece seal kit.
The primary listed replacement reference is Jabsco part 96080-0080. Additional database cross-references associate this seal with Volvo Penta part 818864 and Northern Lights part 25-12066. Verify the number and dimensions on your existing pump or seal before ordering.
- Replacement mechanical shaft seal for compatible sea water pump assemblies.
- Designed for installation after removing and disassembling the pump as necessary.
- Helps restore the seal between the pump shaft and housing and reduce water leakage.

Troubleshooting & FAQ
How do I know if the pump shaft seal is failing?
Water leakage or dripping from the pump weep area is a common warning sign. Rust trails, evidence of water near the bearing housing, or unusual pump noise may indicate that the seal or another pump component requires inspection.
Is this a complete seal kit?
No. This listing is for one replacement mechanical shaft seal. It does not include a pump, impeller, gasket, key, or other service parts unless specifically stated in the order details.
How do I confirm fitment?
Compare the reference on your original seal or pump with Jabsco 96080-0080, Volvo Penta 818864, or Northern Lights 25-12066. Also verify the pump configuration and the seal dimensions before ordering, because engine model alone may not identify the correct pump assembly.
What can cause premature seal failure?
Common causes include running the pump dry, abrasive particles in the raw water, incorrect installation, damaged sealing faces, shaft wear, or corrosion. Make sure the pump has an adequate water supply before operating the engine.
Is this an OEM part?
This listing is for an aftermarket replacement seal. Jabsco, Volvo Penta, and Northern Lights references are provided for identification and cross-reference purposes.
Safety & Important Information
- Close the raw-water seacock and disconnect the battery before servicing the pump.
- Verify the original part number, pump assembly, seal dimensions, and installation orientation before purchase and installation.
- Do not operate the engine if the pump leaks after installation; investigate the seal, shaft, housing, and related components.
- Professional installation is recommended when pump disassembly or shaft inspection is required.
